freight simulation the modal shift transportation planning problem and its fast Steepest Descent Algorithm
Winter Simulation Conference, 2003Co-Authors: Masami Amano, Takayuki Yoshizumi, Hiroyuki OkanoAbstract:The Modal-Shift Transportation Planning Problem (MSTPP) is the problem that finds a feasible schedule for carriers with the minimum total cost when sets of facilities, delivery orders, and carriers are given. In this paper, we propose a fast Steepest Descent Algorithm to solve the MSTPP. Our solution generates a set of candidate routes for each delivery order as a preprocess. Then, it finds a schedule by iteratively updating selections of the candidate routes in Descent directions, while computing a configuration of carrier movements at each iteration by a greedy Algorithm. Intensive numerical study using artificial data modeled from the manufacturing industry in Japan is also presented.

Steepest-Descent Approach to Triple Hierarchical Constrained Optimization Problems
Abstract and Applied Analysis, 2014Co-Authors: Lu-chuan Ceng, Cheng-wen Liao, Chin-tzong Pang, Ching-feng WenAbstract:We introduce and analyze a hybrid Steepest-Descent Algorithm by combining Korpelevich’s extragradient method, the Steepest-Descent method, and the averaged mapping approach to the gradient-projection Algorithm. It is proven that under appropriate assumptions, the proposed Algorithm converges strongly to the unique solution of a triple hierarchical constrained optimization problem (THCOP) over the common fixed point set of finitely many nonexpansive mappings, with constraints of finitely many generalized mixed equilibrium problems (GMEPs), finitely many variational inclusions, and a convex minimization problem (CMP) in a real Hilbert space.

Composite Steepest-Descent method for the triple hierarchical variational inequalities
Filomat, 2019Co-Authors: Lu-chuan Ceng, Jen-chih Yao, Yonghong YaoAbstract:In this paper, we introduce and analyze a composite Steepest-Descent Algorithm for solving the triple hierarchical variational inequality problem in a real Hilbert space. Under mild conditions, the strong convergence of the iteration sequences generated by the Algorithm is established.

Adaptive control of an arc welding process
IEEE Control Systems Magazine, 1993Co-Authors: D.e. Henderson, J. L. Schiano, Petar V. Kokotović, D.s. RhodeAbstract:A pseudogradient adaptive Algorithm is successfully applied to self-tune a proportional-integral (PI) puddle-width controller for consumable-electrode gas metal arc welding. The gradient of the output with respect to the controller parameters is approximated and used to form a Steepest-Descent Algorithm to minimize the squared output error. Experimental data confirming the Algorithm performance are presented.
